The actor is promoting his latest project, in theaters for one night only on Sept. 24.

Evangelical Christian and former Growing Pains star Kirk Cameron has been trying to spread the word about his new movie, Unstoppable.

In it, he examines, "Where is God in the midst of tragedy and suffering?"

But when Cameron put a trailer up on Facebook, it was blocked with the explanation that it was "'abusive,' 'unsafe,' and 'spammy,'" he said.

The move prompted the actor/filmmaker to post a photo of himself with tape over his mouth and put out a call to all "friends of Faith, Family and Freedom" to protest.

He speculated that the religious nature of the film might have been the reason for the block. "I would understand if there was something truly unsafe about my stuff," Cameron told Fox News. "But I would encourage people to watch the trailer. Do you find anything offensive about faith, hope and love in the time of a tragedy?"

A day later, Facebook took down the block, claiming it was the result of "automated systems" that had made a "mistake." A Facebook spokesman also told the Christian Post that the site had been previously registered as a spam site and hadn't been refreshed in it system.

While all seemed well, the same thing then happened on YouTube, until the blocks were again removed.

This week, Cameron, who has been outspoken against gay marriage posted a new note to fans, saying, "People have been asking me to respond to the atheist and activist groups that demand that my videos be removed from Facebook and YouTube. Major media outlets have also been asking me to give my side of the story about why there has been so much hate toward my new project, Unstoppable."

He points them all to a new YouTube video in which talks to the camera saying, "Why do people hate God? ... One, they hate the moral standard. Two, they hate the way he's transforming the world even in the midst of suffering and tragedy."

Unstoppable is being beamed to theaters across the country and will feature a live Q&A with Cameron from Liberty University in Lynchburg, Va., on Sept. 24.
